You could also build that same rectangular prism using cubes,

as shown at the right. If you were then to look at each of the

faces straight on, you would see the views below.

These two-dimensional views of the prism are called

. In this type of drawing, each view
shows only one face, and the angles in the drawing are
congruent to the angles in the actual figure—unlike the
angles in isometric drawings. So a rectangular face is
drawn with four 90º angles.
The drawing at the right is an isometric drawing
of a figure made from 8 cubes.
The drawings below show its orthographic views.

For each set of dimensions, make an isometric drawing of a rectangular prism.

(hheight; wwidth; length).

4.Draw orthographic top, side, and front views of the figure at the right.

5.Discuss and Write Make a rough sketch of your school using isometric and

orthographic drawings. Use centimeter cubes if you need help. Is it easier to

start with isometric or orthographic drawings? Why?

What kind of figure would have the front, side, and top views shown?

Draw the figure.

The figure would be a triangular prism.
